What is 1+1 equal to?
Well, by common sense, it is 2 with no doubt.

However, this is not the case in TNT mechanism in mcpe! 😱

Try to kill an elder guardian with TNTs and you will find out that it will be killed if you ignite a TNT next to it and ignite another after the explosion of first TNT

BUT if you ignite 2 TNTs next to it at the same time, elder guardian will still survive despite taking the same damage theoretically.

Therefore, I learn that 1+1 = 1.1
